' SPECIFICATION forming part of Letters Patent No. 302,047, dated July15, 1884.

I Application filed June 13, 1883. (No model.) I

To all whom it mag/concern.-

Beit known that I, HENRY B. STEvENs, of the city of Buffalo,- in thecounty of Erie and State of New York, have invented new and 5 usefulImprovements in Cane-Mills, of which the following is a specification.

This invention relates to certain improvements in that class ofcane-mills which are composed of three horizontal rollers arrangedtriangularly, and has for its object to improve the construction of theturn-plate which is located between the rollers.

My invention consists to that end of the improvements, which willbe'hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of two sheets, Figure 1 is asectional elevation of a mill provided with my improvements. Fig. 2 is aside elevation of the same mill with a modified construction of thedriving mechanism. Fig.3 is a sectional elevation at right angles toFig. 2. Fig. 4 is a top plan view of the mill represented in Figs. 2 and3. Fig. 5 is a sectional view, on an enlarged scal'e, of the scraper orturn-plate. 'Fig. 6 is an enlarged sectional view of one of the bearingsof the shaft of the turn-plate.

Like letters of reference refer to like parts in the several figures.

A represents the upper or driving roller; A, the feed-roller, and A thedischarge or bagasse roller.

B B are the side frames, supported upon sills b b, which in turn restupon cross-sills b b.

B B are columns formed atboth ends of each side frame, and connectedwith the crosssills b by diagonal brace-rods O, which are secured withtheir upper ends to the upper portion of the columns. The lower ends ofthe 40 rods 0 are provided with hooks c, which engage with hooks asecured to the cross-sills.

, a represents the shaft of the driving-roller A, and a a the lowerstationary portions of the bearings which support the shaft a. l V

D represents the upper movable portion of the bearing, composed ofbrasses d and a cappiece, d. The upper portion, D, of each bearing isheld down by a bent rod, E, which rests with its bent portion 6 upon thecap d, and

extends with its lower ends through the side frames and sills, b, and isprovided below the sills with rubber springs e and screw-nuts andwashers e e.

F is a bridgetree connecting the upper ends of the four columns B.

is a long vertical bearing, formed centrally in the bridge-tree F. G isthe driving-wheel secured to the shaft and g the sweep-cap.

H is the bevel-wheel, secured to one end of the shafta, and engagingwith the crown-wheel G. h is a spur-wheel secured to the opposite end'of' the shaft a, and engaging with spurwheels h on the shaft of the feedand discharge rollers A A, so asto drive these rollers from the toproller.

. In these roller-n1ills having their rollers arranged triangularlythere exists a liability of the cane choking in the triangular spacebetween the rollers, and turn-plates or scrapers have been employed toconduct the cane from the feed to the delivery roller. These turnplatesor scrapers are liable to break under the great strain to which they aresubjected, and it\ is very difliculttto adjust them to the varyingadjustments of the rollers. In my improved mill the turn-plate is soconstructed as to avoid these difficulties.

T represents the turn-plate, which is constructed with a sharp edgefitted accurately to the feed-roller at a short distance below the pointof contact between the feed-roller and the top roller. The turn-plateextends backwardly from its edge eccentrically with the top roller, sothat the space between the plate and the periphery of the top rollerincreases gradually from the edge to the heel of the turnplate.

I i are ribs or flanges, formed along both sides of'the turn-plateI onits upper side, and

projecting between the flanges j of the top roll- 0 from the ends of therollers as the top roller rises and falls in adjusting itself.

It represents a heavy square boss or enlargement formed on the underside of the turnplate, and Z represents a'square shaft, which passesthrough a corresponding opening in the enlargement in. The shaft Z restsin openings m, formed in the side frames, 13, and each bounded by fourconvex sides, as represented Ioo er, A, to prevent the cane from runningoff wheels h, and has the form of a handle, to faeilitate thewithdrawing of the shaft. Upon drawing the shaft out of the turn-plate Iand seats m in the side frames, B, the turn-plate is released and dropsdown between the rollers A A The shaft Z is arranged equidistant fromthe rollers A A and the turn plate can therefore be readily reversed, sothat either of said rollers can be used as the feed or discharge roller,as may be most ,convenient.

1- represents the adjustable bearings, in which the journals of thelower rollers, A A, are

supported; and 0- represents the set-screws, whereby these bearings areadjusted toward or from the top roller, A.

I claim as my invention 1. In a cane-mill, the combination of aturnplate having at its heel an enlargement provided with a squareopening, and a square removable shaft, substantially as set forth.

2. The combination, with the turn-plate and its square shaft, ofsupports provided with openings having four convex sides, by which thesquare shaft is supported and permitted to adjust itself in adjustingthe turn-plate, substantially as set forth.

3. The combination, with the main frame, feed-roller, anddriving-roller, of aturn-plate, I, having at its heel an enlargementprovided with a square opening, a square shaft, l, a handlever, 12,secured to said shaft, and aset-screw, 0, substantially as set forth.
